Back in the 1880s, taking a picture took immense effort. The process of heliography devised by French inventor Nicéphore Niépce, for example, often required exposures lasting several days. Several days. And that was just the exposure. By the time you actually had developed an image you ran the risk of developing age-induced memory loss and forgetting everything you had so carefully calibrated at the outset.

I recently had a headache. Like any reasonable person, I went to the medicine cabinet seeking remedy. After a bit of rummaging around, I ended up with a bottle of generic NSAID (pictured) from which I attempted to discern how many tablets I should take.
